.TH RLOG 1 "\*(Dt" "GNU RCS \*(Rv"
.SH NAME
rlog \- print log messages and other information about \*os
.SH SYNOPSIS
.B rlog
.RI [ " options " ] " file " .\|.\|.
.SH DESCRIPTION
.B rlog
prints information about \*os.
.PP
Filenames matching an \*r suffix denote \*os;
all others denote working files.
Names are paired as explained in
.BR ci (1).
.PP
.B rlog
prints the following information for each
\*o: \*o name, working file name, head (i.e., the number
of the latest revision on the trunk), default branch, access list, locks,
symbolic names, suffix, total number of revisions,
number of revisions selected for printing, and
descriptive text.  This is followed by entries for the selected revisions in
reverse chronological order for each branch.  For each revision,
.B rlog
prints revision number, author, date/time, state, number of
lines added/deleted (with respect to the previous revision),
locker of the revision (if any), and log message.
All times are displayed in Coordinated Universal Time (\*u) by default;
this can be overridden with
.BR \-z .
Without options,
.B rlog
prints complete information.
The options below restrict this output.
.nr n \w'\f3\-V\fP\f2n\fP'+2n-1/1n
.ds n \nn
.if \n(.g .if r an-tag-sep .ds n \w'\f3\-V\fP\f2n\fP'u+\n[an-tag-sep]u
.TP \*n
.B \-L
Ignore \*os that have no locks set.
This is convenient in combination with
.BR \-h ,
.BR \-l ,
and
.BR \-R .
.TP
.B \-R
Print only the name of the \*o.
This is convenient for translating a
working file name into an \*o name.
.TP
.B \-h
Print only the \*o name, working file name, head,
default branch, access list, locks,
symbolic names, and suffix.
.TP
.B \-t
Print the same as
.BR \-h ,
plus the descriptive text.
.TP
.B \-N
Do not print the symbolic names.
.TP
.B \-b
Print information about the revisions on the default branch, normally
the highest branch on the trunk.
.TP
.BI \-d "dates"
Print information about revisions with a checkin date/time in the ranges given by
the semicolon-separated list of
.IR dates .
A range of the form
.IB d1 < d2
or
.IB d2 > d1
selects the revisions that were deposited between
.I d1
and
.I d2
exclusive.
A range of the form
.BI < d
or
.IB d >
selects
all revisions earlier than
.IR d .
A range of the form
.IB d <
or
.BI > d
selects
all revisions dated later than
.IR d .
If
.B <
or
.B >
is followed by
.B =
then the ranges are inclusive, not exclusive.
A range of the form
.I d
selects the single, latest revision dated
.I d
or earlier.
The date/time strings
.IR d ,
.IR d1 ,
and
.I d2
are in the free format explained in
.BR co (1).
Quoting is normally necessary, especially for
.B <
and
.BR > .
Note that the separator is
a semicolon.
.TP
.BR \-l [\f2lockers\fP]
Print information about locked revisions only.
In addition, if the comma-separated list
.I lockers
of login names is given,
ignore all locks other than those held by the
.IR lockers .
For example,
.B "rlog\ \-L\ \-R\ \-lwft\ RCS/*"
prints the name of \*os locked by the user
.BR wft .
.TP
.BR \-r [\f2revisions\fP]
prints information about revisions given in the comma-separated list
.I revisions
of revisions and ranges.
A range
.IB rev1 : rev2
means revisions
.I rev1
to
.I rev2
on the same branch,
.BI : rev
means revisions from the beginning of the branch up to and including
.IR rev ,
and
.IB rev :
means revisions starting with
.I rev
to the end of the branch containing
.IR rev .
An argument that is a branch means all
revisions on that branch.
A range of branches means all revisions
on the branches in that range.
A branch followed by a
.B .\&
means the latest revision in that branch.
A bare
.B \-r
with no
.I revisions
means the latest revision on the default branch, normally the trunk.
.TP
.BI \-s states
prints information about revisions whose state attributes match one of the
states given in the comma-separated list
.IR states .
.TP
.BR \-w [\f2logins\fP]
prints information about revisions checked in by users with
login names appearing in the comma-separated list
.IR logins .
If
.I logins
is omitted, the user's login is assumed.
.TP
.B \-q
This option has no effect;
it is provided for consistency with other commands.
.TP
.B \-T
This option has no effect;
it is present for compatibility with other \*r commands.
.TP
.BI \-V
Print \*r's version number.
.TP
.BI \-V n
Emulate \*r version
.I n
when generating logs.
See
.BR co (1)
for more.
.TP
.BI \-x "suffixes"
Use
.I suffixes
to characterize \*os.
See
.BR ci (1)
for details.
.PP
.B rlog
prints the intersection of the revisions selected with
the options
.BR \-d ,
.BR \-l ,
.BR \-s ,
and
.BR \-w ,
intersected
with the union of the revisions selected by
.B \-b
and
.BR \-r .
.TP
.BI \-z zone
specifies the date output format,
and specifies the default time zone for
.I date
in the
.BI \-d dates
option.
The
.I zone
should be empty, a numeric \*u offset, or the special string
.B LT
for local time.
The default is an empty
.IR zone ,
which uses the traditional \*r format of \*u without any time zone indication
and with slashes separating the parts of the date;
otherwise, times are output in \*i 8601 format with time zone indication.
For example, if local time is January 11, 1990, 8pm Pacific Standard Time,
eight hours west of \*u,
then the time is output as follows:
.RS
.LP
.RS

The first command prints the names of all \*os in the subdirectory
.B RCS
that have locks.  The second command prints the headers of those files,
and the third prints the headers plus the log messages of the locked revisions.
The last command prints complete information.
.SH ENVIRONMENT
.TP
.B \s-1RCSINIT\s0
Options prepended to the argument list, separated by spaces.
A backslash escapes spaces within an option.
The
.B \s-1RCSINIT\s0
options are prepended to the argument lists of most \*r commands.
Useful
.B \s-1RCSINIT\s0
options include
.BR \-q ,
.BR \-V ,
.BR \-x ,
and
.BR \-z .
.TP
.B \s-1RCS_MEM_LIMIT\s0
Normally, for speed, commands either memory map or copy into memory
the \*o if its size is less than the
.IR memory-limit ,
currently defaulting to ``unlimited''.
Otherwise (or if the initially-tried speedy ways fail),
the commands fall back to using
standard i/o routines.
You can adjust the memory limit by setting
.B \s-1RCS_MEM_LIMIT\s0
to a numeric value
.IR lim
(measured in kilobytes).
An empty value is silently ignored.
As a side effect, specifying
.B \s-1RCS_MEM_LIMIT\s0
inhibits fall-back to slower routines.
.TP
.B \s-1TMPDIR\s0
Name of the temporary directory.
If not set, the environment variables
.B \s-1TMP\s0
and
.B \s-1TEMP\s0
are inspected instead and the first value found is taken;
if none of them are set,
a host-dependent default is used, typically
.BR /tmp .
.SH DIAGNOSTICS
The exit status is zero if and only if all operations were successful.

The full documentation for \*r is maintained as a Texinfo manual.
If the
.BR info (1)
and \*r programs are properly installed at your site, the command
.IP

should give you access to the complete manual.
Additionally, the \*r homepage:

has news and links to the latest release, development site, etc.
.SH BUGS
The separator for revision ranges in the
.B \-r
option used to be
.B \-
instead of
.BR : ,
but this leads to confusion when symbolic names contain
.BR \- .
For backwards compatibility
.B "rlog \-r"
still supports the old
.B \-
separator, but it warns about this obsolete use.
